Script Busy error on the Mozilla Firefox browser

Problem: When using a Mozilla Firefox 2.x browser, you might see the error "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or continue to see if the script will complete.",

Solution: When this error displays, you can safely click Continue. This error message can display twice. This means that JavaScript™ code did not execute within the time specified by the default constraint. You can edit the default constraint value to allow the scripts to complete without generating this error.

To edit the default constraint value:
  1. In IBM® Rational® Test Lab Manager, in the URL address field, enter about:config and press Enter.
  2. Find the variable named dom.max_script_run_time. Double-click on the line that contains this variable. A dialog box displays, with the integer value for seconds.
  3. The typical default is between 5 and 10 seconds. Users with slower systems or connection speeds might need to increase this number. Doubling this value should be sufficient to allow the scripts to complete without displaying this error.
